Description

Technical Field

[0001] The utility model relates to the technical field of oil separators, in particular to a vertical oil separator. Background Art

[0002] The screw chiller is a kind of vapor compression refrigerating machine, which includes structures such as a screw compressor, an oil separator, a condenser and an evaporator. The oil separator is located between the screw compressor and the condenser, and can separate the mixture of high-pressure gas and oil discharged from the compressor.

[0003] Generally, a metal wire mesh is arranged in the existing oil separator. It can not only filter the solid impurities in the oil-gas mixture, but also condense the suspended oil particles in the oil-gas mixture into oil droplets. After the oil separator is used for a long time, the metal wire mesh will be blocked by impurities, which will cause the exhaust pressure of the compressor to be too high, easily damage the equipment, and at the same time, the oil separation effect is not good enough. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a vertical oil separator, which solves the technical problem that the oil separation effect of the existing oil separator is poor after long-term use.

[0005] The embodiment of the present application discloses a vertical oil separator, including:

[0006] An outer cylinder, with a containing cavity arranged inside the outer cylinder;

[0007] An intake pipe, communicatively arranged on the side wall of the outer cylinder;

[0008] An outlet pipe, arranged inside the containing cavity, and the end of the outlet pipe extends out of the top of the outer cylinder;

[0009] A deflector plate, installed inside the containing cavity, and the deflector plate corresponds to the end of the intake pipe, and the deflector plate is located outside the outlet pipe;

[0010] A drainage cylinder, installed inside the containing cavity, and the drainage cylinder is located below the outlet pipe.

[0011] The present application is provided with a deflector plate, so that the oil and gas form a centrifugal motion, thereby improving the oil and gas separation effect; at the same time, a drainage cylinder is also provided, which can further improve the oil and gas separation effect.

[0012] On the basis of the above technical solution, the embodiment of the present application can also be improved as follows:

[0013] Further, the end of the intake pipe is higher than the bottom end of the outlet pipe. The beneficial effect of this step is to ensure that the high-speed air flow flows out from the outlet pipe after being processed.

[0014] Furthermore, the drainage cylinder is a cone with a wider upper part and a narrower lower part. The beneficial effect of this step is that the cone can improve the effect of oil-gas separation.

[0015] Furthermore, the outer wall of the upper end opening of the drainage cylinder contacts the inner wall of the outer cylinder;

[0016] A baffle is installed at the lower end opening of the drainage cylinder. The beneficial effect of this step is that the baffle can prevent the oil liquid from being carried out.

[0017] Furthermore, there are gaps between both sides of the baffle and the inner wall of the lower end opening of the drainage cylinder. The beneficial effect of this step is that the baffle can further prevent the oil liquid from being carried out, and at the same time, it does not affect the centralized treatment of the oil liquid.

[0018] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0019] 1. In the present application, by arranging the drainage cylinder and the baffle to cooperate with each other, the oil liquid can be better blocked and prevented from being carried out, effectively improving the oil-gas treatment effect.

[0020] 2. In the present application, the specific size of the baffle is designed, and the baffle is designed to be a smaller size, so that the oil liquid can be better prevented from being carried out. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0033] Embodiment:

[0034] As Figures 1-4 shown, the embodiment of the present application discloses a vertical oil separator for secondary oil separation of a compressor. Compared with the existing separator, it can better achieve oil-water separation;

[0035] As Figures 1-3 shown, the specific structure of the present application includes:

[0036] An outer cylinder 1, inside which there is an accommodating cavity 101 for receiving high-speed air flow;

[0037] An intake pipe 2, communicatively arranged on the side wall of the outer cylinder 1. The intake pipe 2 is horizontally arranged for facilitating the entry of air flow and cooperating with the subsequent deflector to achieve a centrifugal air flow;

[0038] An exhaust pipe 3, arranged inside the accommodating cavity 101, and the end of the exhaust pipe 3 extends out of the top of the outer cylinder 1, that is, the corresponding gas flows out from the top of the accommodating cavity 101 through the exhaust pipe 3;

[0039] The flow guide plate 4 is installed inside the accommodation cavity 101, and the flow guide plate 4 corresponds to the end of the intake pipe 2. The flow guide plate 4 is located outside the outlet pipe 3. In this application, the flow guide plate 4 functions as a flow guide, causing the corresponding gas to form a spiral movement trajectory, so that the oil liquid moves downward along the inner wall of the outer cylinder 1;

[0040] The drainage cylinder 5 is installed inside the accommodation cavity 101, and the drainage cylinder 5 is located below the outlet pipe 3; In this application, the drainage cylinder 5 facilitates the dripping of the oil liquid and can better achieve oil-liquid separation.

[0041] In one embodiment, the end of the intake pipe 2 is higher than the bottom end of the outlet pipe 3, which can ensure better separation of the oil and gas after entry and then exit through the outlet pipe 3.

[0042] Specifically, the drainage cylinder 5 in this application is a cone with a wider top and a narrower bottom. The drainage cylinder 5 in this application is convenient for collecting the oil liquid after it flows, and both its top and bottom are provided with openings. At the same time, there is a gap between the bottom of the drainage cylinder 5 and the bottom of the outer cylinder, so that the oil liquid is concentrated at the bottom of the outer cylinder, which is convenient for subsequent processing.

[0043] In one embodiment, the outer wall of the upper end opening of the drainage cylinder 5 is in contact with the inner wall of the outer cylinder 1;

[0044] A baffle 6 is installed at the lower end opening of the drainage cylinder 5; In this application, the upper end opening of the drainage cylinder 5 is designed to form contact, which is convenient for the oil liquid to drip and finally enter the bottom of the outer cylinder 1.

[0045] Among them, as Figure 4 shown, there are gaps between both sides of the baffle 6 and the inner wall of the lower end opening of the drainage cylinder 5. In this application, the baffle 6 is designed such that it does not completely cover the lower end opening of the drainage cylinder 5, which can better block the bottom of the drainage cylinder 5 and facilitate the high-speed airflow to drive the oil liquid to move upward and flow out through the outlet pipe 3.

[0046] For the convenience of handling, this application can also install components such as lifting rings at the top of the outer cylinder, and a corresponding connecting pipe can also be connected to its bottom.

[0047] In the specification of this utility model, a large number of specific details are described. However, it can be understood that the embodiments of this utility model can be practiced without these specific details.
